Droughts are a real concern because although water is constant, water is not evenly distributed amongst every location on Earth. Many places experience a monsoon season or other extremely wet period, but many other places feature a more desert terrain and climate. In there locations, there is little to no water accessible.
Also, if a normally wet location is experiencing a drought, plants and agriculture that rely on an abundance of water could die, limiting food sources.
The temperature of the substance giving off the heat decreases while the temperature of the substance receilving the heat increases. they leach what is called equlibrium point where heat energy can longer be exchanged hence equql temperature. this isThermal physics
Answer:
We first to know that if the wheel rotates from rest means that at t=0 the velocity and the angle rotated is 0.
Then, we know:
Integrating 2 times, we have:
For the first 27.9 s, we have:
w = 37.107 rad/s
angle = 517.6426 rad
For the next seconds, according to the text, the angular velocity is constant so
w = 37.107 rad/s and hence, integrating:
Then, the time remaining is:
53.5 - 27.9 = 25.6
So for the next 25.6 seconds we have:
Finally, we add the 2 angles and we have as a result:
A because of the resistors are four in this options first option is multiplied by 4
